INTRAOCULAR LENS WITH PERIPHERAL REGION DESIGNED TO REDUCE NEGATIVE DYSPHOTOPSIA
First Claim
1. An intraocular lens (IOL), comprisinga central optic,a peripheral optical flange surrounding said optic,wherein the central optic forms an image of a field of view on the retina of a patient'"'"'s eye in which the IOL is implanted and said peripheral flange inhibits the perception of visual artifacts in a peripheral visual field of the patient.

Abstract
In one aspect, the invention provides an intraocular lens (IOL) that includes an optic and a peripheral optical flange that surrounds the optic. The optic can form an image of a field of view on the IOL user'"'"'s retina and the peripheral flange can inhibit dysphotopsia. By way of example, the peripheral flange can include at least one textured surface that is adapted to receive peripheral light rays entering the eye at large visual angles so as to cause their scattering in order to inhibit dysphotopsia, e.g., by preventing the formation of a secondary peripheral image or scattering some light to a shadow region between such a secondary image and an image formed by the IOL.

27. An intraocular lens (IOL), comprising
an optic comprising an anterior surface and a posterior surface, said optic being characterized as having a central portion extending to a peripheral portion, wherein said optic forms an image of a field of view on the retina of a patient'"'"'s eye in which the IOL is implanted and said peripheral portion is adapted to inhibit the perception of visual artifacts in a peripheral visual field of the patient.

43. A method of correcting vision, comprising
providing an IOL having a central optic and a peripheral flange surrounding said optic, wherein said optic is adapted to form an image of a field of view and said flange is adapted to inhibit dysphotopsia, implanting said IOL in a patient'"'"'s eye.
-
44. A method of inhibiting dyspohotopsia in a visual field of a patient'"'"'s eye in which an IOL is implanted, comprising
providing the IOL with a peripheral portion adapted to receive peripheral light rays entering the eye at large visual angles and inhibiting those rays from causing dysphotopsia.
